Van Gieson Staining Kit

Van Gieson is a technique that is used to differentiate between collagen and smooth muscle in tumor samples. It involves the use of picric acid and Ponceau S dye to stain specific components of the tissue.
When picric acid is combined with the tissue sample, it can easily penetrate into all tissues due to its small molecular size. However, it selectively binds to red blood cells and muscle tissue. This allows for the differentiation between collagen fibers and other components.
To stain collagen fibers, Ponceau S dye is used instead of picric acid. This dye specifically targets collagen and dyes it red, allowing for clear visualization and distinction from other tissues.
The product components required for the Van Gieson staining technique include Celestite Blue Dye (Part A) and Ponceau Dye (Part B), both of which are provided in 100mL packaging.
In summary, Van Gieson staining technique utilizes picric acid and Ponceau S dye to distinguish between collagen and smooth muscle in tumors. This technique relies on the selective binding of picric acid to red blood cells and muscles, while staining collagen fibers with Ponceau S dye. Both the Celestite Blue Dye and Ponceau Dye are essential components of this staining process.

experiment protocol:
1. Place the slices in distilled water;
To stain the nucleus, immerse it in a lapis lazuli dye solution for a period of five minutes. This will allow the dye to permeate and color the nucleus.
3. Rinse with distilled water;
4. Hematoxylin staining for 5min;
5. Rinse with running tap water for 5 minutes;
6. Dye with Ponceau Dye (immersion) for 5 minutes;
7. Use absorbent paper to soak up the moisture;
Transparent ethanol can be rapidly dehydrated and used for mounting purposes.
result:
Cell nuclei are stained blue;
Collagen is stained bright red;
The yellow stain reveals that the cytoplasm, muscle, fibrin, and red blood cells are all affected by it.

To ensure optimal results when using this kit, it is advised that preliminary experiments be carried out. It is recommended to conduct 1 to 2 initial trials.
